Scope

Main Technical Content: 4. Origin 4.1 The environmental quality of the production area shall comply with the provisions of the NY/T 391 "Green Food - Environmental Quality Standards for Production Areas". 4.2 Site Requirements: Although cherries have low soil requirements, from the perspective of economic benefits such as yield and quality potential, it is still recommended to select deep-layered sandy loam soils with convenient irrigation and drainage. The accumulated temperature above 10°C should be between 2,600 and 4,200°C. The absolute minimum temperature should not be lower than -18°C, with an annual precipitation of 400–600 mm. 5. Varieties and Rootstocks 5.1 Varieties: - Early-ripening varieties: Zaodaguo, Russian No. 8. - Medium-ripening varieties: Brooks, Red, Samidai. - Pollination varieties: Meizao, Brooks. 5.2 Rootstocks: Chinese cherries (e.g., Daqingye), Benxi Mountain Cherries, Korting, and Giesela series. 6. Orchard Establishment 6.1 Site Selection: - Soil conditions: Prefer deep-layered sandy loam soils with convenient irrigation and drainage. - Terrain: Build orchards on flat or gently sloping land. Avoid sites with low elevation, poor air circulation, or heavy clay soils. 6.2 Seedling Selection and Treatment: - Standard: Seedlings should be robust, straight, and uniform. The diameter at the grafting site should be ≥1.0 cm, with a height of ≥90 cm (measured from the grafting site). - Requirements: Seedlings should have a well-developed crown, strong root systems with short main roots and numerous, evenly distributed side and fibrous roots. They should have a low stem-to-root ratio (the ratio of the fresh weight of the aboveground part to the fresh weight of the root system). Larger seedlings indicate better growth and quality under similar conditions. - Free from pests, diseases, or mechanical damage. Grafting sites should heal well. - Treatment: Before planting, soak winter-transplanted or externally source
